Fantastic work! A simple concept that still manages to hit the sweet spot with the difficulty. I like how you've added cool details to each level (like unique obstacles such as Marisa getting chased by Alice). It really adds to the charm of the game.
The story's pretty good too, though I think a little bit of art (like a storybook) would make it feel a lot better. I understand that this might be something you've cut due to time constraints, though, so maybe it's something you could add in the future if you'd like?
